The Rapid Evolution of the Internet

The Past, the
Present and the Future

What we are able to enjoy now wasn’t possible in the past.
The technology in this world has well advance rapidly and is still continuing
to evolve. In the past, it was hard to keep in contact with your friend from
another country. It was hard to conduct the different market trends. It was
hard to advertise your product. It was hard to get a business partner. All
these were overcome through the power of The Internet. So now what?

As time passes, opinion changes. Perspective changes and so
does the current trends. I will be going through with you on the current
networking trends that can be beneficial in many aspect.

Network
Reliability

Network must have the capability to ensure that all links(Click here to learn more about connection) are up all the time. If a network isn’t reliable, then downtime will be a very
common problem.

There are 4 key points that have to be met when setting up a
network
1.Fault Tolerance – To have more than 1 connection connected to a
certain place.2.Scalability
– To be able to grow in network size and fit into the network topology/design
due to increasing demands3.Quality
Of Service – To modify the bandwidth priority of traffic so bandwidth is
put to better use4.Security
– To protect the network from intruders. Can increase the security of physical
access as well as implementing extra security system so as to beef up the network security

We all know how dire a solution is
when the network is down. Everyone starts to panic
and chaos arise. A Fault
Tolerant Environment will be able to ensure that when a disaster do happen, the
impact done to the equipment are kept to the minimal. This is important because
it will allow faster recovery time. The damage done to the organization is also
reduce greatly depending on the kind of accident that happen. There are 2 kinds
of Fault tolerance1.Fault
Tolerance in a circuit switch·Makes use of the load balancing concept. Have
many path to the same destination. However only one path will be chosen. If the
chosen path is down, remaining system will still be functioning. This allows
for the network to continue as usual as if nothing has every happen.2.Fault
Tolerance in a Packet Switch·Similar to circuit switch fault tolerance. The
only difference is that the redundancy link is also use when there is no error.
Data is usually broken up into smaller packet and encapsulated with the source
and destination address. They are then send separately over and de encapsulated
at the destination

There has to be something connecting all the devices
together. The Media of the Network is what is used to combine all the device
together. We currently have 3 different kind of media which we use so as to
transmit data from one end to another.

IP addressing and Subnetting

Beep Beep Beep! Did I manage to catch your attention? I sure
hope I did for this topic will be the base of the entire networking course.
This is because we will be going through the relationship of IP addresses
(Internet Protocol Address) and Subnet Mask.

How Packets Communicate

Imagine a world without languages. What will be the common
ground for our ideas and opinion to interact with each other? What will happen
to the innovation we all are seeking for? That’s the same when it comes to the communication
done on the network.

We know how the message is transferred from one place to
another. But do we know what the message is. That is what we will be
discussing.

Explanation of a Router, Switch and Hub

Hey there, remember in the earlier post where I elaborate on
what an end device is? Well now we will be introducing another kind of device
which is the Intermediary Device. This device main purpose is to deliver or
send out your request over to the destination. It is like a the journey from
point A to point B. It is used to CONNECT up end devices together

The
Different kind of Network

Today I will be teaching you all the differences between LAN
and WAN as well as how the Internet came about. This concept is one of the
basic concept you need to understand in order to go on with the other topics.
